چکیده:

Most of the reported control algorithms for uninterruptible power supplies use either inductor currents or capacitor currents of their filter as feedback variables to regulate the output voltage. This paper proposes a simple non linear control using current and voltage of a DC/AC inverter of an isolated three phase power network. Theoretical analysis and simulation results demonstrate fast response, and develop a good performance. This nonlinear control algorithm is applicable to both single-phase and three-phase systems. Theory and simulation results are presented in the paper.
